Description

Verfahren zur Darstellung von Verbindungen der Morphiumalkaloide mit Barbitursäurederivaten. Durch Patent 32233j ist ein Verfahren zur Darstellung von therapeutisch wertvollen Verbindungen der Alkaloide der Morphiumgruppe geschützt, welches darin besteht, daß man auf die Alkaloide der Morphiumgruppe Diallylbarbitursäure entweder in Form der freien Verbindungen oder in Form ihrer Salze in molekularen Mengen, gegebenenfalls in Gegenwart geeigneter Lösungs- oder Verdünnungsmittel, einwirken läßt.Process for the preparation of compounds of the morphine alkaloids with Barbituric acid derivatives. By patent 32233j is a method for the representation of therapeutically valuable compounds of the alkaloids of the morphine group are protected, which consists in the fact that one on the alkaloids of the morphine group diallylbarbituric acid either in the form of the free compounds or in the form of their salts in molecular form Quantities, if appropriate in the presence of suitable solvents or diluents, can act.

Es wurde nun «-eiter gefunden, daß man zu therapeutisch ebenfalls wertvollen Verbindungen der Alkaloide der Morphingruppe gelangen kann, wenn man in dem Verfahren des Hauptpatents die dort verwendete Diallylbarbitursäure ersetzt durch Arylalkylbarbitursäuren, wie z. B. Phenvlätlivlbarbitursäure. Die so dargestellten Verbindungen sind in ihrer @'4irkung nicht nur der in der Patentschrift 239313 beschriebenen Verbindung aus Codein und Diäth-,-lbarbitursäure ebenfalls um ein Vielfaches überlegen, sondern sie besitzen größtenteils auch die für die Verbindungen mit Diallylbarbitursäure charakteristischen neuen Wirkungen.It has now been found that therapeutically valuable compounds of the alkaloids of the morphine group can also be obtained if the diallyl barbituric acid used in the process of the main patent is replaced by aryl alkyl barbituric acids, such as e.g. B. Phenolic barbituric acid. The compounds shown in this way are not only many times superior in their action to the compound of codeine and dieth -, - lbarbituric acid described in Patent Specification 239313 , but they also have, for the most part, the new effects characteristic of the compounds with diallylbarbituric acid.

Dieses Ergebnis ist entschieden überraschend, da keineswegs vorausgesehen werden konnte, daß sich bei dem vorliegenden Verfahren die Arylalkylverbindungen ähnlich verhalten würden wie die Diallylbarbitursäuren, vielmehr mit großer "Wahrscheinlichkeit vorauszusehen gewesen wäre, daß beispielsweise die Verbindungen aus Phenyläth3Tlbarbitursäure analoge Wirkungen auslösen würden wie die entsprechenden Verbindungen aus der ihr chemisch und therapeutisch viel näher stehenden Diäthylbarbitursäure. In der Tatsache, daß entgegen dieser Erwartung den Verbindungen aus Arylalkylbarbitursäuren die wertvollen und eigentümlichen Wirkungen der entsprechenden Diallylverbindungen, nämlich die gleichzeitig schmerzstillenden, schlaferregenden und wehen-- fördernden Wirkungen zukommen, die sie zu der therapeutisch so wertvollen Verwendung als Dämmerschlafmittel unter der Geburt geeignet erscheinen lassen, liegt eine überraschende technische Wirkung begründet.This result is decidedly surprising as it was by no means foreseen could be that in the present process, the arylalkyl compounds would behave similarly to the diallyl barbituric acids, but with a high "probability" It would have been foreseeable that, for example, the compounds from phenylethylbarbituric acid would trigger effects analogous to those of the corresponding compounds from the her chemically and therapeutically much closer diethylbarbituric acid. In the fact that contrary to this expectation the compounds from arylalkylbarbituric acids are valuable and peculiar effects of the corresponding diallyl compounds, namely the at the same time analgesic, sleep-inducing and labor-promoting effects which makes them therapeutically so valuable as a twilight sleep aid Making it appear suitable during childbirth is a surprising technical one Effect justified.

Beispiel Z.Example Z.

69,6 g Phenyläthylbarbitursäure und 9o,9 g Morphin werden im Paraffinbad geschmolzen und bei dieser Temperatur zo Minuten belassen. Nach dem Erkalten wird das Reaktionsprodukt aus Alkohol unter Zugabe von etwas Blutkohle umkristallisiert. Die Morphin-PhenS,-lä thylbarbitursäure scheidet sich in Form weißer Nadeln vom Schmelzpunkt 25o" C ab. Sie ist in Alkohol leicht, in Wasser, Benzol und Aceton schwerer löslich. $eispiel -,. . 69,6 g Phenyläthylbarbitursäure und 99,3 g Athylmorphin, werden ,mit Zoo g Benzol am Rückflußkühler 1A Stunde gekocht. Beim Erkalten scheidet .94 ai h linorPhin-Pheny1-äthylbarbitursäure in Forxn weißer Nadeln aus, die bei 87' C schmelzen. Die Verbindung ist in Wasser ziemlich schwer, in den gebräuchlichen organischen Lösungsmitteln leicht löslich. Beispiel 3. "6b,6.g. Phenyläthylbarbitursäure und 95,1 g Codein werden mit Zoo g absolutem Alkohol 1/2 Stunde am Rückflußkühler gekocht, hierauf erkalten gelassen, wobei sich die Codein-Phenyläthylbarbitursäure.inForm weißer Kristalle ausscheidet. Die neue Verbindung schmilzt bei 8o' C, ist in Wasser ziemlich schwer, in den gebräuchlichen organischen Lösungsmitteln leicht löslich. 69.6 g of phenylethylbarbituric acid and 9o.9 g of morphine are melted in a paraffin bath and left at this temperature for zo minutes. After cooling, the reaction product is recrystallized from alcohol with the addition of a little blood charcoal. 69.6 g ,. Phenyläthylbarbitursäure and 99, - The morphine PhenS, -lä thylbarbitursäure separates as white needles melting at 25o "C. It is light in alcohol, in water, benzene and acetone less soluble $ EXAMPLE... 3 g of ethylmorphine are boiled with zoo g of benzene on the reflux condenser for 1 hour. On cooling, .94 ai h linorphine-pheny1-ethylbarbituric acid is excreted in the form of white needles which melt at 87 ° C. The compound is quite difficult in water Easily soluble in common organic solvents. Example 3. "6b, 6.g. Phenylethylbarbituric acid and 95.1 g of codeine are boiled with zoo g of absolute alcohol on the reflux condenser for 1/2 hour, then allowed to cool, the codeine-phenylethylbarbituric acid separating out in the form of white crystals. The new compound melts at 8o'C, is quite heavy in water, and easily soluble in common organic solvents.

An Stelle der in den Beispielen verwandten Alkaloide können die verschiedenen anderen Alkaloide der Morphingruppe, wie z. -B. Diacetylmorphin, Allylmorphin, Benzylmorphin oder die verschiedenen Derivate der Morphiumalkaloide, wie z. B. deren HYdrierungsprodukte, ferner -'#pomorphin, Apocodein, usw. verwendet werden. Ferner kann die Phenv läthylbarbitursäure ersetzt werden durch andere Arylalkylbarbitursäuren.Instead of the alkaloids used in the examples, the various other alkaloids of the morphine group, such as. -B. Diacetylmorphine, allylmorphine, benzylmorphine or the various derivatives of morphine alkaloids, such as. B. their hydrogenation products, also - # pomorphin, apocodein, etc. can be used. Phenylbarbituric acid can also be used are replaced by other arylalkylbarbituric acids.
